abstract = "Neotropical primates are among the most well studied forest
mammals concerning their population densities. However, few
studies have evaluated the factors that influence the spatial
variation in the population density of primates, which limits the
possibility of inferences towards this animal group, especially at
the landscape-level. Here, we compiled density data of Sapajus
nigritus from 21 forest patches of the Brazilian Atlantic Forest.
We tested the effects of climatic variables (temperature,
precipitation), landscape attributes (number of patches, mean
inter-patch isolation distance, matrix modi- fication index) and
patch size on the population density using linear models and the
Akaike information criterion. Our findings showed that the density
of S. nigritus is influenced by landscape attributes, particularly
by fragmentation and matrix modification. Overall, moderately
fragmented landscapes and those surrounded by matrices with
intermediate indexes of temporal modification (i.e., crop
plantations, forestry) are related to high densities of this
species. These results support the assumptions that ecologically
flexible species respond positively to forest fragmentation.
However, the non-linear relationship between S. nigritus density
and number of patches suggests that even the species that are most
tolerant to forest cover changes seem to respond positively only
at an intermediate level of habitat fragmentation, being dependent
of both a moderate degree of forest cover and a high quality
matrix. The results we found here can be a common response to
fragmentation for those forest dweller species that are able to
use the matrix as complementary foraging sites.",
